LG Dryer: loud noise during operation

Professional Repair Guide

What is this symptom?

Are you experiencing loud noises from your LG dryer during operation? These disruptive sounds could indicate issues like foreign objects in the drum, an obstructed blower wheel, or worn drum bearings. Addressing these concerns promptly can prevent further damage and ensure your dryer operates smoothly.

Urgency: Medium

Important Tips for LG Models

  • LG support notes that some operational sounds (humming compressor, gurgling from drain pump) are normal, but unusually loud noise warrants inspection.
  • Normal airflow humming and certain cycle related sounds may be present per official LG documentation.

Possible Causes

Obstructed or damaged blower wheel

How to Identify: Grinding, scraping, or vibrating noise coming from lower rear; airflow reduction.

Part: Blower wheel

Worn drum bearings or glides

How to Identify: Squeaking or grinding continuous through cycle; marks or metal shavings inside drum.

Part: Drum bearings/glides

Unbalanced load / overloading

How to Identify: Thumping noise when drum spins heavy/uneven loads; noise reduces after adjusting load size.

Part: Load distribution

Dryer not level

How to Identify: Rumbling or vibrating noise; dryer wobbles when door open.

Part: Leveling feet/frame

Normal operational noises

How to Identify: Mild humming or gurgling during specific cycle functions, not overly loud.
